TYPE-WRITING MACHINE.

, SIPEGIFIGATION forming part of Letters Patent No. 485,761, dated November 8, 1892. Application filed April 4, 1889. Serial No.'305.960. (170 model.)

To all nzhom it may concern:

York, have invented certain new and useful Improvements in Type-Writing Machines; and [do hereby declare the following to beam full, clear, and exact description of the inven'. tion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of typewriting machines in which the type or charactors are carried on the periphery of a type wheel or sector which. by the depre sion of the appropriate key is oscillated. to bring .a. determined letter or character opposite the impression devices.

One object of my invention is to dispense with the multiplicity of mechanical parts now employed to eilect the operation of this clas of machines.

A further object of the. invention is to secure a uniform stroke or impact on the type whether the keys are operated with a light or heavy touch.

A further object of the invention is to operate the type-wheel and impression devices through the agency of a'storage orother electric battery the current-of which is controlled from the keyboard.

A further object of the invention is to en able me to actuate the type-wheel and other operative parts of the machine by a slight de pression of the keys.

With these and minor objects in view the invention consists in novel features of con struction and combinations to be claimed in the clauses at the close of this specification.

In the accompanying drawings, Figure 1 is a side elevation of'a type-writing machine embodying my improvements. Fig. 2 is a plan view of the same. Fig. 3 is a detail rep resenting one of the keys depressed. Fig. 4'

is a detail perspective of a part of one of the keys. Fig. dis a similar view of onset the upper-case ornunleral keys. Fig. 6 is a. perspective view of ,the type-wheel collar. Fig.

Above the bed A Or i le ma'chinepare keys B, supported upon a fulcrum or fnlerums a, rising from'the bed. These keys B, I prefer to arrange in two series separated by anontral'spaci'ng-key B, and in order to economize lateral space I prefer to arrange the keys of the keyboard in two banks, as shown. In order to provide for the printing of upper-case lettors, numerals, &c., I construct the keys in three parts-namely, the key proper B, an up per-case key b,'consisting of a strip of metal formed 'at its forward end to overlap the key B and secured at its rear end to the shank of said key by a horizontal pivot b, and a numeral-key b', constructed and arranged in a manner similar to the upper-case key and secured to theother side of the key proper b the same pivot b.

Extending across the machine between the outer ends of the keys and the bed A is a light plate 0, supported upon a skeleton frame 0', (which I shall term a shifting frame) fnlcrnmed just forward otthe keyfulcrumson posts a, rising from the bed and extending at its rear end just beneath the type-wheel shaft to be presently described. Just forward of the fulcrnms' of the shifting frame and arranged centrally with relation to the keyboard is a. post- Aflto the upper end of which is secured by a vertical pivot a driving-rod D, the free end of which extends'back to near the type-wheel shaft and is provided with a geared sector d.

The type-wheel shaft E is mounted in a hollow post A, rising from the center of the bed well toward the rear and is encircled at its lowerend by a coiled spring a, tending to hold the shaft'in the lowermost of the three positions it may assume. The upper end of the type-wheel shaft is provided with a shoulder, above which is loosely mounted a type wheel or sector .E', carrying three series of letters on its face, arranged as is usual in this type of machines, and just below the hub of the type-wheel is loosely mounted a collar e",

provided at its upper end with a pinion e,

arranged to mesh with ,thetoothed sector d,

and at its lower end with two stop-arms'e -e, eachprovided on their inner faces with a so.-

ries oi serrations or notches a, corresponding in number tothe numberlofkeys' in a series.

For instance, we will assume that the'machine is provided with thirty keys B, exclusive of the spacing-key, fifteen on each side. of the center or spacing key B, or, in other words,

E, thus locking the type-wheel to said stoparm.

At points about midway between the keyfulerums a and the type-wheel post A two pairs of posts a and a are secured to the bed A, and overlying the keys of each series in rear of their t'ulcrums are light bars F, the 'rearwardly-cranked ends F of which are pivotcd, respectively, to the posts of a pair-say cfl-neartheirupperends. The upperendsof these posts a, alsocarry two forwardly-projectlng pivoted armsff' and a fixed arm f proyidedwithinsulatedcontact-pointsl234. The lower pivoted armf is supported at its free end by the rearwardly-cranked arms F of the rod F and moves with it against the pressure of a light spring secured to the post a ,while the pivoted arm f is supported parallel to but free from contact with the armsf' and f by a fixed lug projecting from the post (L2. Two light insulated conductors 2O 21 lead from the positive pole of any suitableelectrical battery to the two contact-points 2.

and 3, carried byarmsf', the contact-point 1 on the lower armfbeingconnected bya single insulated conductor 22 with a pair of magnets 5, arranged one above the other on the right of the shifting-rod D, and supported upon bracket-arms A secured to the bed A. The magnets 5 are in turn connected with theother pole of the battery by an insulated conductor 23. The contaet-pointt of the upper fixed arm f is connected by an insulated conductor 2% to a pair of hammer-magnets 6, supported in rear of the paper-carriage, and pivot-ed in front of these hammer-magnets is a lever provided at its lower end with an armature 7, arranged abreast of the cores of the hammer-magnets, this lever being provided at its upper end with a hammer designed to force the paper against the type of the typewhecl. Thehammer-magnetstiareconnected to the negative pole of the battery by a conductor 25. The devices just described relate to the control of the electric current by the right-hand series ofkeys only; but it will be understood that the left-hand series of keys are providedwitha cranked rod G, actuating contact-carrying arms 9 g g and magnets 5 through conductors 20 21 22 23* and contact-points 1 2 3 and at constructed and arranged in all respects similar tothe corresponding devices already described in detail. The drivingmod D is provided with an arms.-

lVith this arrangement the stop-arms the posts A, rising from the bed.

-thet'ype -wheel collar e.

tnre arranged opposite the cores. of the respective pairs of magnes 5 and. 5 in order that said driving-rod may be moved to the right or left according as the right or left driving-magnets 5 or are rnerg zed. 7

To the lower end of the post 'A", in which the type-wheel shaft is mounted, is secured a rearwardly-projecting lug provided on opposite sides with hearings in which are seated the inner ends of rock-shaft L, the outer ends of which are seated in bearings carried by These shafts L are provided at each end with forwardly-projectingarms Z Z of unequal length, the ends of which are connected by alight rod 1*. The outer or shorter arm Z terminates just forward of the rear ends of the outermost keys of each series and thewconnectingrods, Z? rest upon the rear ends of the keys of each series, but, owing to the greater length ofthe inner arms'l', cross said keys diagonally, as shown in Fig. 2. The rock-shafts L have secured to them near their inner endsvertical arms 1 the'upper ends of which terminate just above the stop-arms e and e of These rock-shafts, with their arms i, i, r, and rods Z form, in effect,1evers, which Ishall term stop-levers. their purpose being to stop or check the stoparms c and e positively at such a point as will bring the desired letter of the type-wheel directly opposite the impression-hammer, and also to restore the type-wheel and its adjuncts to a normal position when the key is released. To fulfill the latter function, it will be necessary to either weight the horizontal armor arms of the lever or connect to them a stout spring or springs Z, the stress of which shall be exerted to press the horizontal arm of the lever downward The paper-carriage which is. mounted just in rear of the type-wheel may correspond in general outline with that now used on the Hammond machine, and the feeding-roll,rversin g devices, and escapement may also be arranged and operated like those used on the Hammond carriage. I pre fer, however, to employ a feed and escapement for the carriage similar in all substantial particulars to those now in common use for the same purpose in the Remington type- .writer and contemplate controlling the escapement-tingersby angled levers'h, pivoted at a point in rear of the type-wheel post and having their forward ends extending just past the rear ends of the ke'yslS and connected by a light rod h, resting upon said rear ends of all the keys of both series.

In order to provide, for the printing of a line or lines upon paper of more than usual width, I have devised a paper-carriage constructed of two sections I I, each of the length other approved form, The outer section I is providedinteriorly with oppositely-arranged grooves t, designed to receive correspondinglyarrenged ribs c", secured to or forming part of the inner section I, end the outer section I is provided with a spring-pressed latch 17, one end of which is design ed to engage one ot the notches i or '6 formed in the opposite ends of 1 the inner section to lock the sections together i in a folded or extended position, as desired. It will be understood, of course, that intermediate notches may be formed, as indicated, to lock the sections together at points between thelimits of adjustment. The notch i should be quite deep to prevent the latch from slipping, but the other notches should be shallow or their ends beveled in order that the sections may be adjusted by endwise pressure on the sections in opposite directions. The inner section I of this carriage is provided with the usual feeding-rolls end their ad jllllC/iS, and as the right-hand edge of the paper will have no support from the fecd-rolls when the sections are extended I secure within the right-hand end of the inner section a light vertical partition. I and a similar partition 1 within the right-hand end of the outer section to hold the exposed part of the pepcr l? upright in front of the typewheel to prevent false alignment. In printing upon paper of a width equal to the whole length of the extended carriage the sections are first folded together and a line printed of a length equal to the length of the folded carriage. The carriage is then restored to its first position, but without actuating the feed-reil, and the catch 1 is Withdrawn from the notch i in the left-hand end of the inner section, and said inner section is then drawn out to its full extent and the latch 9? released to engage the notch c" in the righthand end of said inner section, thus locking the sections together in their extended position, when printing may be resumed as in the first instance.

in operating the machines a depression of A the key Bwill lift the cranked rod F, and

an equal distance toward the left.

with it thelowcrarmf, untilits contact-point it meets the contact point 2- on arm f. This establishes an electric circuit irombsttery 50 through the wire 20 to end through the contact-points 2 and l, thence through wire 22 to the driving-magnets 5, then back to the battery through wire 23, thus energizing ina ncts5 to attract the armatnres Set the driving rod and moving the shifting-rod toward the right.- Owing to themeshing of the pinion c with the geared sector (1 on the drivingrod, the type-wheel collar 6 will be rotated and move the stoparm c toward the left, at the same time owing to the connection of the iypecrheel E with the types-wheel collar by means of the pin c, moving said type-wheel During this operation the inner end of the key depressed will raise the lower arm of the stoplever L and move the vertical arm of said lever rearward a determined distance, Where the upper end of the vertical arm of thelever will arrest the stop-arm is and the type-wheel.

These varied actions take place almost simultaneously during the time that the outer end of the key has but partly completed its downward movement, and the continued movement of the key operates to raise the cranked arm F to such a height that the arm f will be carried upward by the arm f until contact is established betweenjthe points 3 and 4, and this completes an independent circuit from the battery through wire 21, con

tact-points 3 and 4, wire 24 to the hammermagnets, and thence through wire 25 back to the battery. The energizing of the hammermagnets by this second current attracts the armature 7 and causes the hammer to strike the paper againstthe letter or character, presented. The depression of one of thekeys of the left-hand series results in. the same action, as the cranked arm will first raise the arm g to make contact between the points 1 and 2 of the arm g and 9', thus establishing a circuit through wire 20", points 2- and 1 and wire 22 to the, magnet 5 and thence back to the battery through wire 23", the hammermagnets being operated from the left-hand series of keys through thewires 21", points 3 and 43, and wire 24* to the hammer-magnet, and thence back to the battery by wire 25.

As the upper row of characters on the typewheel will be the lower-case type, it follows that it-will not be necessary in printing the lower-case letter to raise the type-wheel, and therefore-theupper-case and numeral keys b. and b, owing to their pivotal connection with the shank of the main key, will have no iniluence upon the shifting frame when said main key is depressed. Those keys 6 b have IOO depending from their free ends studs b and b overhanging the plate 0 of the shifting frame C. The stud on the end of the uppercase key b is shorter than that of the numoral-key b, for the reason that the second row of type on the type-wheel is comprised of upper-case letters and the third row ofnumorals. Therefore, the depression of the upper-case key, while carrying the main key B down with it, will necessarily complete the circuits in the manner described and at the same time raise the type-wheel to' its second position to bring the upper-case letters opposite the hammer, and a like manipulation'of the numeral-key b will have the sameresult, except that owing toits longer stud b" the shifting plate will be depressed a greater distance, thus raising the type-wheel higher.

As before stated, the stop-lever is designed to stop and hold the type-wheel at the point where a determined letter or character on said wheel is presented to the action of the hammer, notwithstanding the continued attraction by the driving-magnets of the armamust be made with some accuracy to obtain a perfect impressions. It is with this purpose that l have provided the inner edges of the stop-arms e and e with notches corresponding in number to the number of keysin a series. Thus there being inthe instance shown fifteen keys on each series there must be fif-- teen notches in each of the stop-arms, each presenting a flat face, against which the upper end of the stop-levers will abut without danger of slipping.

Owing to the diagonal arrangement of the connecting-bar Z of the stop-lever, it crosses the successive keys (from the inner to the outer key) of a series at progressively-greater distances from their fulcru'ms. Therefore the depression of the inner key of a series will move thislever but just enough to bring the end of its vertical arm Z in the path of the first notch of the stop-arm, thus arresting said arm and the type-wheel which is connected with it by the pin before mentioned ata point where thefirst letter or character from the center of said wheel willreceive the blow of the hammer. The depression of the outer key of. a series will in like manner move the stop-lever the greatest possible distance to place the end of its vertical arm in the path of the last notch on the stop-arm, thus arresting the stop-arm and wheel at a point where the outermost letter or character on the face of thedatter will receive the blow of the hammer.
